Sylpheed 0.9.7, GnuPG, GnuME and trouble with the gpg-support in Sylpheed

[Rembrandt <rembrandt_(_at_)_jpberlin_(_dot_)_de>]

I installed oBSD (again) on my Notebook last night (couse I installed nBSD
for testing the ACPI support of the 1.6.2rc3).

After the install I installed XFCE from ports, gpg, gpgme and sylpheed.
Sylpheed dosn't recorgnize gpg.

Coulde somebody help me to solve this problem couse I don't know why
sylpheed dosn't recognize gpg.
I build all these programms from source on my "old" oBSD 3.4 (stable) 
and it works fine. :o/

Thanks for any reasons. ;o)
